    How to cool down Mineral Oil

    Hello friendly people of PF So I have a tank with about 250 litres of mineral oil in it. and computer servers are immersed in it. the oil keeps the servers cool but get's hot in return. What different (economic) ways are there to cool the oil down? The best way I could think of was Oil-water...

    Lifetime of an oil filter compressor

    Hi, I'm doing an internship about mechanical maintenance. I have come to a problem that is a bit over my head. The problem was also discussed by a few process engineers but they did not come with a good solution. So, the oil filter is part of a biogas compressor. The biogas comes from the...

    Do petroleum engineers struggle with ethical dilemmas?

    Petroleum engineers are smart, educated individuals. Therefore, I’d assume they’re well aware of the environmental impacts caused by the work they do. Do they ever struggle with any ethical issues regarding the matter? Is it the money? Is it the possibility of making oil drilling processes more...

    I Oil-Water-Salt - What's the force at work here?

    Hi, This is something I observed in the kitchen when I was cooking something. I had put some water in a vessel, to which, I added couple of spoons of oil. The oil formed large droplets on water surface. I then sprinkled normal table salt crystals on to the water surface and they sank to the...

    Millikan Oil Drop Experiment: Determining Elementary Charge

    Homework Statement Calculate the charge on each oil drop and determine the elementary charge on an electron given the following: Voltage (Attached) d (Distance between two charged plates) = 0.10m m (Of the droplet) = 1.57x10^-15 kg g = 9.8 kgm/s^2 Homework Equations q = mg*d / ΔV The Attempt...

    Oil & water problem

    How does a ball floating 50% in water move when a large amount of oil is added, and why? MY Solution: I think that the ball rises because when a large amount of oil is added, the oil sinks to the bottom causing the water to be pushed up, increasing the buoyant force which causes the ball to...

    Honeycomb structure of oil due to an electric field

    Hi, I've been working on a problem for some time now and I can't figure out why exactly this happens, and I've been looking for some insight. The phenomenon can be seen in this video. We can see that the oil rearranges itself due to a high-voltage electric field. Thinking about this, my...

    Change in gravity due to oil deposit

    Homework Statement "A mining company finds gravity is 2 parts in 10^7 less over a certain area. Assume there is an oil deposit 3000m below. Take the density of rock to be 3000 kg/m^3, and the density of oil to be 1000 kg/m^3. Estimate the mass of the deposit, assumed spherical." Homework...

    I need information on centres of mass

    Hi I am doing an assignment where I roll a tin can filled with car oil. This will affect its rolling because it distorts its centre of mass, resulting in an awkward rolling motion. I have already done the experiment, the first revolution is the slowest one by a lot because it slows down a lot...

    Carbon Emissions

    Hi there, Could someone explain to me why fossil fuels, such as coal and oil, produce fewer particulate matter emissions than natural gas? Also, how would you expect the combustion temperature of these fuels to affect particulate emissions? Would a higher temperature lead to a more complete...
